A) Reimer-Tiemann reaction
B) Cannizaro reaction
C) Wurtz reaction
D) Friedel-Crafts acylation
Correct Answer: B
Solution :
Reimer-Tiemann reaction, (Here, a new C?C bond is formed.) Cannizaro reaction, \[\text{2HCHO}\xrightarrow[{}]{\text{Conc}\text{.}\,\text{NaOH}}\text{C}{{\text{H}}_{\text{3}}}\text{OH}\,\text{+}\,\text{HCOONa}\] (No new C?C bond is formed in this reaction.) Wurtz reaction, \[2RX+dry\,Na\xrightarrow[{}]{Ether}R-R\] (One new C?C bond is formed.) Friedel-Crafts acylation, (New C?C bond is formed.) Thus, among the given reactions, only Cannizaro reaction does not involve the formation of a new C?C bond.You need to login to perform this action.
